Answer:
Thank A is draining <u>faster than</u> Tank B because the <u>slope</u> of the graph for Tank A is <u>steeper than</u> that of the graph for Tank B.
The <u>slope</u> of the graph tells you the unit rate in gallons per minute.
Step-by-step explanation:
The slope of a graph is also known as the gradient of a line graph or surface. It is basically a number that shows the steepness and direction of a line graph or surface.
The steeper a line graph or a surface is, the faster an object falls from it.
From the graph, Tank A is steeper than Tank B, therefore, gas will drain faster from Tank A than Tank B.
Since gas is measured in gallons, the slope of the graph therefore tells you the unit rate in gallons per minute.
